mlib_ImageColorRGB2Mono(3MLIB)				    mediaLib Library Functions				    mlib_ImageColorRGB2Mono(3MLIB)

NAME

       mlib_ImageColorRGB2Mono - RGB to monochrome conversion

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageColorRGB2Mono(mlib_image *dst, const mlib_image *src, const mlib_d64 *weight);

DESCRIPTION

       The  mlib_ImageColorRGB2Mono()  function  performs  a conversion from a red/green/blue to a monochromatic image. The source image must be a
       three-channel image. The destination image must be a single-channel image.

       It uses the following equation:

       dst[x][y][0] = weight[0]*src[x][y][0] +
		      weight[1]*src[x][y][1] +
		      weight[2]*src[x][y][2]

PARAMETERS

       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source image.

       weight	       Array of three blending coefficients. It is recommended that these sum to 1.0, but it is not required.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

NAME

       mlib_ImageColorConvert1_Fp - color conversion using a 3x3 floating-point matrix

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageColorConvert1_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *cmat);

DESCRIPTION

       The  mlib_ImageColorConvert1_Fp()  function takes a 3x3 floating point conversion matrix and converts the floating-point source color image
       to the destination color image.

       The source and destination images must be three-channel images.

       It uses the following equation:

       |dst[x][y][0]|	|cmat[0] cmat[1] cmat[2]|   |src[x][y][0]|
       |dst[x][y][1]| = |cmat[3] cmat[4] cmat[5]| * |src[x][y][1]|
       |dst[x][y][2]|	|cmat[6] cmat[7] cmat[8]|   |src[x][y][2]|

PARAMETERS

       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source image.

       cmat	       Conversion matrix in row major order.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
